United States Patent O 3,468,506 BRACKET Sandy T. Curlee, Cary, N.C.,assignor to Curlee Machinery Company, Inc., Cary, N.C. Filed Apr. 26,1967, Ser. No. 633,815 Int. Cl. F16m 13/ 02; F21v 33/00 U.S. Cl. 248-2212 `Claims ABSTRACT OF THE DISCLOSURE This invention relates to a bracketfor holding a street light or sign.

Lightweight street light brackets are ordinarily composed of taperedaluminum tubes which are produced by spinning a large diametercylindrical aluminum workpiece. This requires the use of expensivespinning equipment.

The object of this invention is to produce a hollow lightweight tapered'bracket of pleasing appearance which is suiciently strong for holding alight or a sign, and the making of which does not require the use ofexpensive spinning equipment.

In general, this object is obtained by forming a bracket of an uppermember joined to a lower member by means of triangular side plates.These plates are welded to the members by spot welds which arealternately spaced along the length of the side plate. The location ofthe welds together with the plates gives a truss-like construction whichis of pleasing appearance, is adequately strong, and is inexpensivelyfabricated.

Alignment rods are placed in grooves in the outer end portion of thebracket for facilitating the assembly of the bracket.

The means by which the objects of the invention are obtained aredescribed more fully with reference to the accompanying drawings inwhich:

FIGURE 1 is a `front elevational view of the bracket;

FIGURE 2 is a cross-sectional view taken on line 2 2 of FIGURE 1;

FIGURE 3 is a cross-sectional view taken on the line 3 3 of FIGURE l;and

FIGURE 4 is a cross-sectional view taken 0n the line 4--4 of FIGURE l.

The bracket is composed of as upper member 10, a lower member 12 and `apair of triangular side plates 14 and 16. The upper and lower membersare respectively downwardly and upwardly concave and preferablysubstantially semi-cylindrical, and except for the outer end portion 18are inclined with respect to each other. The base end portion 19includes the triangular side plates 14 and 16. Each side plate hasbeveled edges 20 which are seated in corresponding grooves 22 inlongitudinal edges on the upper and lower members and 12, respectively.

The side plates are secured to the upper and lower members by means ofspot welds atlernately spaced along the longitudinal length of the sideplates. Welds 24 and 3,468,506 Patented Sept. 23, 1969 ICC 26 are on theinterior wall surface of the bracket while welds 28 and 30 are on theoutside surface of the bracket. As these welds are alternately spaced onthe upper and lower members, they form a triangular path which resemblesa truss construction. The use of spot Welds rather than continuous weldsreduces the weight of the bracket.

In the outer end portion 18 starting at the position for weld 30, theedges of both the upper and lowery members 10 and 12 are provided withgrooves 31. Alignment rods 32 are seated in these grooves to keep theouter end portions aligned during assembly. The free end of the bracketis secured by spot weld 34 located inside the bracket, this weld joiningthe upper member 10 to the lower member 12.

The bracket is mounted on a base plate 40 having an oval rib 42. Thebase end of the bracket is seated within the rib 42 and joined theretoby means of a weld 44.

The completed bracket can then be secured to either a wood or metal pole50 by means of one or more bolts 52. An opening 54 is in the bottom oflower member 20 for the passage of electric wires. A street light orsign can be hung on the end portion 18 by any conventional means.

Having now described the means by which the objects of the invention areobtained,

I claim:

1. A bracket adapted to be attached to a pole for holding a light or asign comprising an upper downwardly concave member, a lower upwardlyconcave member, a pair of triangular side plates, beveled edges on saidplates, grooves in said upper member and said lower member coextensivewith said plates and into which said beveled edges are seated, alignmentgrooves in thc edges of the outer end portions of the upper member andthe lower member, alignment rods seated in said alignment grooves forforming a joint between said upper member and lower member, rst spotwelds alternately spaced on said upper member and said lower member andalong said plate joining each member to the plates, and second spot.welds directly connecting the upper member to the lower member alongsaid alignment rods.

2. A bracket as in claim 1, said rst and second Spot welds beingalternately placed on the inner and outer surfaces of said bracket.
